Abstract

This document describes techniques and apparatuses for gesture-based content-object zooming. In some embodiments, the techniques receive a gesture made to a user interface displaying multiple content objects, determine which content object to zoom, determine an appropriate size for the content object based on bounds of the object and the size of the user interface, and zoom the object to the appropriate size.

Claims

1. A computer-implemented method comprising:

determining a center point of a multi-finger zoom-in gesture having momentum, made over a user interface, and received through a gesture-sensitive display;

determining, based on the center point, a content object of multiple content objects in the user interface;

determining a size at which to zoom the content object based on one or more bounds of the content object and a size of the user interface; and

causing the user interface to zoom the content object to the size.

2. A computer-implemented method as described in claim 1, wherein determining, based on the center point, a content object of multiple content objects includes:

determining a preliminary content object in which the center point resides;

determining, based on a size of the preliminary content object and the size of the user interface, whether the preliminary content object can substantially fill the user interface at a maximum resolution of the user interface; and

if the preliminary content object can substantially fill the user interface, setting the preliminary content object as the content object, or

if the preliminary content object cannot substantially fill the user interface, setting a parent content object of the preliminary content object as the content object.

3. A computer-implemented method as described in claim 2, wherein setting the parent content object as the content object includes finding the parent content object based on a logical division tag of the preliminary content object and within a document object model having the logical division tag subordinate to a parent logical division tag associated with the parent content object.

4. A computer-implemented method as described in claim 1, wherein determining, based on the center point, a content object of multiple content objects includes:

determining a preliminary content object in which the center point resides;

determining, based on a current size of the preliminary content object and the size of the user interface, whether the preliminary content object substantially fills the user interface; and

if the preliminary content object does not substantially fill the user interface at the current size, setting the preliminary content object as the content object, or

if the preliminary content object does substantially fill the user interface, setting a child content object of the preliminary content object as the content object.

5. A computer-implemented method as described in claim 4, wherein setting the child content object as the content object includes finding the child content object based on a first logical division tag of the preliminary content object and within a document object model having the first logical division tag superior to a second logical division tag associated with the preliminary content object.

6. A computer-implemented method as described in claim 4, wherein setting the child content object determines that the child content object is closer to the center point than one or more other child content objects.

7. A computer-implemented method comprising:

determining, based on a multi-finger zoom-in gesture having momentum, made over a user interface, and received through a gesture-sensitive display, a content object of multiple content objects in the user interface; and

zooming the content object to bounds of the content object effective to substantially fill the user interface with the content object.

8. A computer-implemented method as described in claim 7, wherein zooming the content object completely fills the user interface with the content object and ceases to present others of the multiple content objects.

9. A computer-implemented method as described in claim 7, wherein zooming the content object displays a progressive zooming animation from an original size of the content object to a final size of the content object.

10. A computer-implemented method as described in claim 7, wherein zooming the content object displays a snapping animation.

11. A computer-implemented method as described in claim 7, further comprising, responsive to a pan gesture made over the user interface and received through the gesture-sensitive display, panning the content object within the bounds.

12. A computer-implemented method as described in claim 11, wherein panning within the content object does not display others of the multiple content objects previously presented prior to zooming the content object.

13. A computer-implemented method as described in claim 11, wherein the bounds represent two horizontal bounds of the content object and panning the content object within the bounds pans vertically through the content object and within the two horizontal bounds.

14. A computer-implemented method as described in claim 7, wherein zooming the content object presents the content object at a new, final size without displaying a progressive zooming animation.

15. A computer-implemented method as described in claim 7, further comprising zooming out the content object within the user interface to an original size responsive to receipt of a multi-finger zoom-out gesture having momentum.

16. A computer-implemented method as described in claim 7, further comprising zooming the content object beyond the bounds responsive to receipt of a second multi-finger zoom-in gesture.

17. A computer-implemented method comprising:

receiving a multi-finger zoom-in gesture having momentum, made over a user interface, and received through a gesture-sensitive display on which the user interface is displayed;

determining, based on a center point of the gesture, a content object of multiple content objects in the user interface;

determining two or more bounds of the content object; and

zooming the content object within the user interface to the bounds.

18. A computer-implemented method as described in claim 17, wherein zooming the content object is responsive to determining that the gesture has the momentum.

19. A computer-implemented method as described in claim 17, further comprising, following zooming the content object to the bounds, receiving a pan gesture made over the user interface and received through the gesture-sensitive display, and, responsive to receiving the pan gesture, panning within the content object.

20. A computer-implemented method as described in claim 17, wherein the user interface is a webpage, the content object is non-advertising content, and one or more of the others of the multiple content objects are advertising content.
